su rer The object of the'invention to pro hoe new, simplified and readily operated meansfor supporting such spare rims. I

Fig. 2'is a transverse sectional View partly broken away i-llustratihg one form of my invention designed to accommodate two de mountable rims with applied inflatedtires.

Fig. 3 is a View in side elevation illustrating; the two positions of one of the eccentric cam like-members employed to engage the.

demountahle rim "to hold position. a Fig. 4 is it in supported an enlarged detail of onev of a pair of plates between which each eccentric wedge member is mounted.

Fig.6 is a View in side elevation of the bracket support.

Referring in detail to the Various views, 1 indicates a spring or cross frame member of an automobile chassis to which is attached the'loracket support for holding the spare rims. This bracket support in the illustrated embodiment may comprise a curved supportingrod or bar 2 suitably fastened to the spring or frame cross member 1 by means of a detachable clamping device 3 or otherwise. This rod 2 carries a triangular supporting frame comprising parts 4, 5 and 6,

the extremities of which are joined together and fastened by means of the connecting members 5 and- 5 A pair of strut rods-2 connect theltwc upper c'ornersof the triangular frame with Specification of Letters Patent.

the bar 2, in order to. add rigidity to the supporting frame as a whole. Carried by the connecting members 5? and 5 at the three corners of the triangle and projecting therefrom are rods which may it it so desired form continuations oi the members 2 and 2, in which case they would penetrate ftheconnecting members 5 and 5". These rods 9 form supports for the tire rimclamping instrumentalities and where desired they 1naybe of sullicient length to accommodate two sets of suoh instrumentalitics in order to take care of two spare tii'e rims as shown in 2. The rim clamping devices, which ta'lre the form of eccentric cams, are mounted upon the rods 9 between plat/es 7-3 The eccentric cams are rotatable upon the rods 9 and are indicated by the numeral 10. lz'hese cam devices when in active supporting position, as shown in dott d outline (see F1g.' 3) engage the inncr clrcumierential surface of [the tire rim at equi-distant points at the corners oil the triangular frame. Each cam is provided with an operating handle 12"to afford ready manipulation. y

In order to additionally support the tire inposition, I may employ metal straps 13,

the ends of which are sprung into suitable slots 14 in the plates i (see Fig. t). It will he manifest that when the handle 12 oi. the operating cams 'are manipulated to bring the cam surfaces into engagement with the tirerim {see d l the rim with its applied inflated tire will he forced outwardly against thexinetal straps, thus resulting in nrcssure being applied to both tire and rim, which re sults in holding; the tire rigidly in position.

In order to hold the cam devices in rim loch:

lng position, the locking pin 15 (see Fig. 2}

may be conveniently inserted throughthe alined apertines-lo of the plates aius lccl-ring the handle in its active position and holding it there against accidental di 'dgment. In order to prevent the handles swung in the IBVQloQ or unlocking dire ,1". 1 to too great an extent, a similar locking; pin may be inserted in the alined apertures '2'? thus serving; as a limiting; stop to such back ward movement.

In order to prevent unauthorized removal. of the spare tires from the support, suit; 11g means may be provided; 'llhi filu t in making the outer plate 7 with a per mated extension Sf forming the head assing the bow olxa padlock 5 thereie pin 15 with a similar perforation 8*".

t sition engage the inner circumtereutial surtace oi? the tire rim and that all of the -ams are mounted so that their active cam surt'accs Will be brought into operative position vhen being thrown outwardly or away from a the center. It will be manifest from this that rims of varying diameter may be accommodated by su 'iporting means of the described character. The variability in this respectbeing only limited by the particular shape and size of the eccentric :LIIlS.

Tlhile I have describral one m'eterable embodiment of the principles ot my invention, do so by way of example and it do not wish to be limited in the matter of structu al dc tails as these may be changed or varied without departing from the spirit and scope of the invention as defined by the following claims.

Havin thus described my invention what '1 claim as new herein and desire to secure by Letters Patent is:

1. In a tire bracket tor supporting demountable rims, the combination ot a pair of perforated plate members. a shaft penetratmg eccentric member journaled upon said between saidplate members, a handle operating;- said eccentric member and a loc ing pin insert-ible through the peitorations ot said members tor retaining said eccentric in tire rim engaging position.

2. Means for supporting demountable tire rims including a triangular trame like supporting bracket. eccentric cam members pivotally supported on the triangular support said eccentric lllGIl'lbOl'S being provided with cam edging surfaces adapted to engage the inner peripheral surface of a den'iountahle rim and operating handles for oscillating the eccentric members.

2-5. A b 'ackct support for spare automobile tire rims including a series of plate members supported adjacent to the demountable rim when in supported position, eccentric cam members pivotally mounted between said plati members, means for operating said eccentric men'ibers and strap members encircling' the tire and fastened to. said plate members.

l. hleans tor supporting a. spare demouutable rim, including a plur; lity o't eccentric cam members, supporting means for said cam members. said cam members being provided with cam \vedgring surfaces adapted to engage the demoluitable rim at spaced apart points along the inner peripheral surface thereof and operatinghandles for ()$lCllltllIiI'l the eccentric members, substantially as described.

said plate members, a rim cngagi l l llil'illhll i SHAJN ON.
